this is pretty cool. Not about to try it in the garage or anything. http://www.freepatentsonline.com/4083340.htmlGasoline superheater Document Type and Number:United States Patent 4083340
Wierd...either the patent holder forgot that PV-nRT or there's a lot more to it than what's in the description. Devon
Hey paolosica, this is George aka fatboybuick, you have a 72 2 door limited also now!!! I just seen it on cardomain and she's also a beauty, I can't seem to get the money together for your four door, with out it causing a major financial problem for me, but I would say keep them both that's a beautiful collection you got there, keep in touch. :TU:
Would that simply improve atomization once the fuel is mixed with the air? What other benefit would there be? A gallon of gas is a gallon of gas. Also, isn't superheat the amount of heat added to a vapor after it has transferred from the liquid to the vapor state? That is the definition I am familiar with. Nick
Heres an interesting excerpt from the article, emphasis mine "We have tested the Superheater experimentally for over 39,500 miles on two different automobiles. One of these is a 1970 Ford Galaxie Sedan fully equipped and a 1972 Buick LeSabre Sedan also fully equipped. We found an average 72% increase in miles per gallon (MPG) mileage on the open highway at speeds of from 50 to 55 miles per hour (MPH). We found a 42.degree.-46.degree. increase in city suburban highway combination driving. We also ran dynamometer tests on the 1970 Ford using a 1 gallon jug of gasoline. Two different dynamometer tests so run gave an increase of about 100% in gasoline mileage. The testing machine was set at 10 Horsepower (HP) road load and run at 40 MPH. The result showed 26.4 MPG. Incidentally we found that Hydrocarbon (HC) and Carbon Monoxide (CO) emissions were reduced by 86% and 87% respectively. Conservative figures show a 40% increase in mileage (MPG). We actually averaged about 70% increase in MPG on both the Ford and the Buick. Pollution has been reduced on the Ford by 87% on HC and 86% on CO. No such tests have been made on the Buick but our observation indicates pollution decrease at about the same percentages.
No question that heated gasoline burns more readily and more completely- better MPG and better emissions. That's part of the reason that Buick used 195 degree thermostats in many engines. Ideally you would want freezing cold air (more dense in the cylinder for best power) and hot (liquid) gasoline. From what I understood, "superheating" means keeping it pressurized so that the hot fuel stayed in liquid form. -Bob C.
interesting....so why isnt this an option we can buy? Have the oil companies squased these things?? or what? Is it dangerous to cmpress and heat liquid gas? sounds like it. 70% difference is a big deal. Why isnt this being done? Anyone have any real insight?
Gary, from a theoretical standpoint lots can be done toward this sort of thing. From a financial standpoint, the ends do not justify the means. This is coming from me, a fuel/brake systems engineer and diehard gearhead. My headache is bad enough I'll not get into the long-haired theory on this one tonight. Suffice to say hot fuel and cold, dense air do not like to be married to each other for much longer than an instant. They try to get to "lukewarm" together and that's what we're dealing with...and have been for a long time. Devon
Suffice to say hot fuel and cold, dense air do not like to be married to each other and that's assuming the air is 'cold' in the first place. you mix 100 degree air with 'superheated' gas and you won't have any density in the cylinder.
99% of patents granted are on worthless and impractical ideas for one reason or another. Depending on the breath of the claims getting one can be easy. They never amount to anything except another stack of paper in Crystal City. I can tell you stories about some applications that would make you fall on the floor laughing but sadly the Patent Office is full of those.
Hi Guys, There is a grain of truth to the "high mileage" carburetor, but carburetor technology has never been able to match fuel delivery with engine demand very well across the operating range. Then we get to the "driveability" of the vehicle, does it bog, hesistate, stumble on aceleration or idle rough? Also, heating fuel and cooling air do require some additional energy, so there may not be as much fuel savings as advertised. The "new" technology in the automotive world is GDI (gasoline direct injection), where the fuel is injected into the combustion chamber, much like a diesel. These engines produce more power, have lower emissions and better fuel economy than a traditional port fuel injected engine!:3gears: The fuel system costs are greater and there is an interesting component added to the engine to produce high pressure for the GDI system; they have a camshaft actuated mechanical fuel pump! Now, how do I fab one up for my Nailhead? Tim:Comp:
interesting component added to the engine to produce high pressure for the GDI system; they have a camshaft actuated mechanical fuel pump! loads of extra stress on the cam gear/bearings, just what we need with a Buick! the diesel big rig guys have hydraulically actuated fuel injectors coming but they're already driving so much they'll never notice the extra crank load.
One other item that superheated fuel adds besides increased atomization is the potential for an explosion inside the intake manifold. If you look back at the Smokey Yunick experiments he noted there was a very fine line between the ideal temperature for the atomization of gasoline and an overheated fuel mixture. When it worked, it was great for mileage and emissions, but when it didn't it was very dangerous. Smokey made it work, but then again, he was one of the few people that could. I wonder how many of those little 4 cylinder mopars he blew up before he got it right. Later, Randy
